| Abstract: |
| Based on the data of the Tarim River Basin for 8 years before and after the implementation of river length,using a regression discontinuity model combined with qualitative analysis,studying the effectiveness of the river chief system in the Tarim River Basin and exploring its internal causes, the results show that:(1) The river chief system has a positive effect on the water environment governance of the Tarim River Basin;(2) However, the effect on the improvement of river water quality is small, only 1.4% per year, and the reduction of heavy pollution is only 0.8% per year;(3) The reason is that the policy has been invalidated early due to the late start, the imperfect interest linkage mechanism has led to the misplaced implementation of rights and responsibilities, and the low participation of the masses.The study makes the following recommendations: further implementation of the burden-sharing mechanism;innovative interest linkage and mass participation mechanism;further improve the supervision and management mechanism,promote synergy from the aspects of innovation of regulatory entities, innovation of supervision methods, and innovation of evaluation indicators,earnestly promote the construction of a long-term mechanism for the governance of the water environment by the river chief system.In order to provide a scientific basis for further exerting the function of the river chief system and promoting the sustainable governance of the water environment. |
